DISCHARGE MECHANISM FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 484,923, dated October25, 1892.

Application filed April 6, 1891- $erial No. 387,805. (No model.)

To aZZ whom it may concern.-

Be it known that we, WILEY N. STROUD, residing at Waxahachie, county ofEllis, State of Texas, and RUFUS H. COREY, residing at Auburn, county ofCayuga, State of New York, citizens of the United States, have inventeda new and useful Improvement in Discharge Mechanism for Harvesters, ofwhich the following is a specification.

Our invention relates particularly to the binder-deck of harvesters; andit consists, broadly, of a flexible deck having its lateral edges fixedand its middle portion hinged at one edge and free at the other, andmeans for automatically lowering the latter when the bundle of grain isto be discharged in order that the discharge may be facilitated.

It further consists of details of construction and operation hereinaftermore fully described, and particularly pointed out in the claims.

Figure 1 is an end View of the binder-deck of a harvester embodying ourinvention, showing the working parts of the binder in side elevation.Figs. 2 and 3 are similar views, showing the relative positions of thedeck and discharge-arms and the binder mechanism just before and at thetime of the discharge, respectively. Fig. 4 is a View of the deck,looking in the direction of the arrow, Fig. 1. Fig. 5 is an edge view ofthe deck, looking upward. Fig. 6 is an edge view of the deck, lookingdownward.

A represents the deck; B, the dischargearms; C, the hinges upon whichthe deck swings; D, the rods or links by which the free edge of the deckis raised or lowered.

The binder mechanism is of the usual form, except that to the crank E,by which the compressor-fingers F are withdrawn when the bundle is to bedischarged, is attached one end of the links D, the other end beingattached to the free edge of the deck. The crank E is actuated by thespring-link I, the latter being actuated by the cam J. The dischargearmsB operate in the usual manner, revolving simultaneously with the cam J,and being so located upon the shaft that as the compressor-fingers arewithdrawn the dischargearms pass over the deck and the deck is loweredsimultaneously by the links D, attached to the crank E, and thedischarge of the grain thereby facilitated. The links D may, ifpreferred, be actuated by any other suitable mechanism entirelyindependent of the binder mechanism, provided its movement is properlytimed to lower the deck at the time of discharge.

We prefer to construct the deck of three different partsthe,middleportions 1) b,which are hinged, the end portions a a, which are securelyattached to the frame of the machine and do not move, and theintermediate portions 0 0, connecting these two, made of some flexiblematerial-such as sheet metal which will bend when the middle portion israised or lowered. This forms a more-substantial and less-cumbersomedeck than one in which the, entire deck swings on hinges, and it has thefurther advantage of giving, when raised, a narrow contracted space inthe middle immediately under the breast-plate H and falling off at eachside, where the large ends of the bundle come, and without having anyjoints or crevasses into which the grain may fall and obstruct theoperation of the machine. The middle portion b of the deck is mostconveniently constructed in two separate parts with a link D under each,raising and lowering them together; but, if preferred, they may be madein one and only a single link required.

We do not wish to limit ourselves to the exact construction of the deckshown or the means for raising and lowering it at the proper time, asthe same may be slightly varied without departing from the spirit of ourinvention.

WVhat we claim, and desire to secure by Letters Patent, is-

1. The herein-described discharge mechanism, consisting of thecombination of the binder-deck having the movable middle portion, thefixed ends, the flexible intermediate portions, and means forautomatically raising and lowering said middle portion, allsubstantially as shown and described.

2. The herein-described discharge mechanism for harvesters, consistingof the combination of the binder-deck; A, having its middle frame of themachine, and the flexible intermediate portions 0 c joining them, andmeans i 5 for automatically raising and lowering the middle portion, allsubstantially as shown and described.
